Hello Friends,

I am working on a new design for Shear Drill Collar Ram, I would like to ask if anybody can give me a suggestion for the material, metallurge and surface coating.

Thanks in the advance.

Really? How is it that you are designing something and you have no idea of what materials to use?
Sounds like you need to make some serious patent infringements.

Reality used to affect the way we thought. Now we somehow believe that what we think affects reality.
